Does the puppy have an otherwise good temperament/personality? I think underbites are quite common in Golden litters. If you love him, it would only make sense to keep him. If you dont like the personality of the puppy or something, that is different. I have never known of an underbite to develop into something serious. I just cant imagine returning one for that reason unless i was going to be passing down those genetics for some reason. Good luck

Any more info on the underbite issue. Need all the help I can get to make this decision. Wife is already attached to the dog and I am fighting my affection.
Does anyone have pics of older dogs with underbite? Do they look different?

One of the labs I fostered this past winter had an underbite . She was 6 yrs old and you couldnt even tell it when her mouth was closed. It didnt bother her at all. She could eat and chew on bones and it didnt seem to phase her a bit.

Good luck but if its only an 1/8" of inch why does your vet say return the pup? does he not think it may correct itself or get better when the pup gets older? The lady i foster for had a pup that had either a underbite or overbite cant remeber which and as he got older he still had it but it wasnt nearly as bad as it was when he was a pup and again it didnt phase him once bit. He was sold as a pet though since he couldnt be shown or bred.

My biggest concern is this GR starting to look like a bulldog. I spoke to several vets today who say this could get worse with age. Do not mean to be cruel but I want a nice looking GR whether I show her or not. Sorry, please help more.

I went back and read this thread a few times. Did you say how old the puppy is? I apologize if you did. If your puppy still has puppy teeth, there is no way to tell what the adult teeth will look like. A slight under or over bite will have no effect on the outward appearance of your puppy. If your not breeding or showing, I can't imagine why you would be concerned. In addition, the shape of your puppy's jaw will contine to change until it is at least a year old.

I had a german shepard that had a underbite. He lived along time. If your not using your dog for a show dog, then I dont see what the problem is. The most that will happen is a dental bill that will shave the teeth so they do not dig into the gums, then the teeth will be capped. If you return the pup to the breeder usually they will put them to sleep. Thats what the breeder was going to do with my shepard,so we kept him, and just paid the dental bill. This was our second shepard that had a under bite. The first shepard we tried braces. Looked really funny, cost alot but wasnt as effective as shaving the teeth down and caping them.

The only difference between a dog with a over or underbite is the fact of they have a bit more difficulty picking up something off the ground... As well.

Our shepard lived til he was 12 with the over/underbite and you coudlnt even tell. For a vet to tell you, honestly i dont care what vet to say a dogs underbite/over bite will get worse through age is terrible. A vet can not perdict it due to the baby teeth. If you want me to send you a pcitre of our shepard who had the over/underbite email me and I will send you the picture sheri_kasper@hotmail.com
